If we knew then what we know now….Adapting to meet challenges
Gulf Coast

U.S. Fish & Wildlife Service
A surrogate species approach, why is it something we need to do? 1. Only a fraction of the landscape is devoted to species
conservation (prioritize conservations lands)
2. Finite resources are allocated to conservation as it competes with other socioeconomic objectives ($$ = best conservation value)
3. The vast majority of species habitat requirements remain unknown (utilize data rich areas)

• Baseline information to determine habitats vulnerable to change, and areas less vulnerable
• Prioritize areas for sustainable conservation
• ID candidate sites for refuge expansion, mitigation banking, and other conservation approaches
